If it is fungus lower the water temperature to 76. Higher temperatures encourage fungus to grow and I think you said his water is at 79... Try to clean the tank every day, at least siphoning the bottom without ever removing him.

Did you dissolve the salt first?

Okay I turned off the heater because it is not adjustable to keep the temp a bit lower. I'm gonna be home all day so I will watch the thermometer to make sure the temp stays good. Room temp is pretty good. Yes I watched a youtube video on how to add AQ salt to tanks. So I dissolved the salt first then added it to the tank. His color is much better he is just mopey right now.

I would do 1tsp/gall for a day and then you might need to increase it to 2tsp/gall. Aquarium salt can be up to 3tsp/gall.
Make sure you dissolve salt first in one gall and shake it well. Don't add it directly to his container. Make sure you acclimate him to new water...

How would I know to increase the salt dosage? Yep I dissolved it in a separate container first then added it to his tank. Yeah I always make sure I acclimate him to his new water. My Raz just doesn't like 100% water changes. They stress him out.

give us update how he doing and will see if you need to increase the dosage. How you acclimate him. Is the new temperature inappropriately the same as his? Try to add a little bit of new water in his changing, cup let him get used to it for about 5 min,and do it 2-3 times. This way he will not ever fell the difference,

Okay I will def keep everyone updated. Yes that is what I do to acclimate him. I put some of the water from the tank into his cup wait 15 mins. Then do a little bit more. Wait another 15 mins. The temp is pretty much the same temp. I think what stresses him is being taken out of his tank. I am very gentle when I take him out and put him back. I guess my little guy is just more sensitive.
